[jira] [Commented] (CALCITE-5346) Support for type aliases

    [ https://issues.apache.org/jira/browse/CALCITE-5346?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17706583#comment-17706583 ] 

TJ Banghart commented on CALCITE-5346:
--------------------------------------

I opened CALCITE-5621 for root schema UDT declarations. It appears that {{root}} might be this global value - or at least acts like it when type lookups are performed for DDL and CAST statements.

> We would like to support some sort of type alias functionality in order to map certain [BigQuery types|https://cloud.google.com/bigquery/docs/reference/standard-sql/data-types] to ISO types, e.g. {{STRING}} &rarr; {{VARCHAR}}, {{BYTES}} &rarr; {{VARBINARY}}.
